FRANK'PASTORIUS, OF QUINCY, ILLINOIS.

IMPROVEMENT IN MOWING-M ACHINES.

Specification forming part of Letters Patent No. 182.383, dated September 19, 1876; application filed 7 February 14, 1 876.

To all whom it may concern: V

Be it known that I, FRANK PASTORIUS, of Quincy, in the county of Adams and State of Illinois, have invented a new and useful Imment has been applied, taken through the line at m, Fig. 2. Fig. 2 is a top view of the same.

Similar letters of reference indicate corresponding parts,

The object of this invention is to furnish an improved device for giving motion to the sickle-bar o'f reapers and mowers, which shall be simple in construction, effective in operation, easily driven, and not liable to break or get out of order.

The invention consists in the combination of the two cams, the two pairs of bevel-gear wheels, the shaft, and the pair of gear-wheels with the axle of the drive-wheels, and with the oscillating lever that vibrates the sicklebar, as hereinafter fully described.

A represents the frame of a reaper or mower. Bis the axle, which revolves in bearings attached to the frame A, and to which the drive-wheels are attached. The drivewheels are not shown in the drawings. To

the axle B, or to one of the drive-wheels, is

attached a large gear-wheel, O, the teeth of which inesh into the teeth of the small gearwheel D, attached to the end of the shaft E. The shaft E revolves in bearings attached to the frameA, and to its middle part are attached two bevel-gear wheels, F, which are placed near each other, and back to back, and are rigidly connected with each other and with the shaft E. The teeth of the two large bevel-gear wheels F mesh into the teeth of two small bevel-gear wheels, G, the journals of which revolve in bearings in'an upright frame, H, attached to the main frame A. To the upper ends of the journals of the gearwheels G are rigidly attached two cams, I, set in opposite directions, so as to alternately V push against the opposite sides of the end of the lever J, and thus oscillatethe said lever. The leverJ iscurved downward and forward, is pivoted to the frameA, and its otherend is designed to be connected with the sicklebar, so that the said sickle-bar may be vibrated by the oscillation of the said lever J. The friction between the cams I. and the lever J may be lessened by a rubber or other roller pivoted to the said lever J. The cams I may also have rollers pivoted to them. Having thus described my invention, I claim as new and desire to secure by Letters Patenti a y The combination of the two cams I, the two pairs of gear-wheels G F, the shaft E, and the pair of gear-wheels D G, with the axle B of the drive-wheels, and with the oscillating le ver J, that vibrates the sickle-bar,"substam tially as herein shown and described.

FRANK PASTORIUS.
